台湾海峡自然条件及隧道方案初步研究

台湾海峡跨海工程是国家高速公路和铁路网的重要组成部分，也是巩固国防、应对突发事件、维护和平发展环境的需要，跨海通道建成后将会加快大陆与台湾经济一体化进程，满足两岸交通运输不断增长的需求。从国内外同类工程可以看出，台湾海峡通道前期工作量巨大、技术复杂、难度大，所需的时间较长。在研究台湾海峡的气象、水文、地质条件等的基础上，对桥隧方案及隧道线位方案进行了初步比选分析，认为台湾海峡跨海工程宜采用铁路隧道，并且平潭-新竹的隧道线位方案较优，在对该线位浅埋隧道和深埋隧道的比较后认为采用深埋方案较优。由于公路隧道存在诸多技术难题，以及工程造价和运营成本都很高，因此，把铁路隧道方案作为首选方案是可行的，汽车可通过穿梭列车背负过隧道。

Research on engineering geological problems and the railway tunnel plan on taiwan strait

The Taiwan strait sea-crossing engineering is the national highway and an important part of the rail network, also be to strengthen national defence, the response to emergencies, maintain peace development environment of need, after the completion of cross-sea channel will speed up the mainland and Taiwan economic integration, and meet the cross-strait traffic transportation growing demand. From domestic and foreign similar engineering can be seen, the Taiwan strait channel workload is huge, and the technology is complex, difficult, and the required time is long. In the research of the Taiwan strait meteorological and hydrological, geological conditions of the foundation, on the bridge and tunnel scheme line a preliminary scheme than the election analysis, thought the Taiwan strait sea-crossing engineering should use the tunnel, and the Pingtan-Xinzhu tunnel line is a better solution, After the comparison between a line of shallow buried tunnel and a line of deep buried tunnel, we come to a conclusion, the later is the better.. Because there are many technical problems, when we are facing the construction of high way tunnel. And also the construction cost of  highway tunnel and operation cost are very high, therefore, the railway tunnel scheme as a preferred scheme is feasible, car can travel by train carry through the tunnel.
